      It’s not a great video partly because I was new, but it give a more “realistic” view on what you see before processing

    Unfortunately TH-cam lowered the quality of the final image, so i've posted the Image into my community section for you guys to see in higher quality :)

    I noticed you're shooting through an open window and there's a heat radiator/register just below the window. The rising warm air will affect the seeing conditions. Even if you turn off the heat source it will take a while for the heat to dissipate.

      I didn’t even of this, I have actually moved house now and will be shooting from outside with every session from now on. So hopefully my seeing conditions improve slightly, cheers mate :)

    Without a tracking mount, you still can take images at short exposure-times, like 1/4 s. M42 is bright enough as to allow for this. I have done this with my 190/1000 Mak-Newt when I did not have a tracking on my EQ5 yet.
    Simply capture a series of 1/4 s frames and put them into DeepSkyStacker. Any longer exposures at a focal length beyond 600 mm or so will definitely produce star trailing blur, obviously also in M42 itself. More than a second is too long, I'm afraid.

    • @ASTR0FILMS
      @ASTR0FILMS  2 ปีที่แล้ว

      True, I need to find a stacking program for Mac and then I can get on to doing this, hopefully I can get some better results :)

    • @Guido_XL

      @@ASTR0FILMS There are some Mac applications out there that offer stacking capability, like Siril and Nebulosity. I cannot tell you anything useful about them though, as I only used DeepSkystacker on Windows, which works quite well with large stacks of images.
      Picking M42 was a good choice, as it is quite bright, so that short exposures are feasible. For most other deep sky objects, tracking is kind of mandatory.

      @@ASTR0FILMS you could consider running a virtual machine with Windows and the stacking program. I see no reason why it shouldn't work.

      Using the "Rule of 500," the max exposure you could take is 0.4 seconds to avoid trails. However, you would be better to use a telescope mounted on a motorized equatorial mount to get a much better image

    Just a thought, try locking the the mirror up prior to exposure.

    I'm in the southern Hemisphere.. Did Orion too a couple nights ago... we have fairly nice weather, and no light pollution.... we have a lot of wind though, and that screws with the tracking alot on my "Newtonian-cloud-maker-delux". When I still used my Canon, I loaded Magic-larntern on it, for doing amazing timelapses/ long exposures and whatnot, no need for a remote shutter at all...

    • @ASTR0FILMS

    Quite nice to see something like what I actually see through my telescope, rather than the high res, hours of integration images that some astrophotographers achieve. I mean they are very impressive, but don’t give a realistic impression of what you can actually see visually.

    • @ASTR0FILMS

      Ah thanks so much, your right it is nice to see, maybe one day I’ll be able to produce 15 hour long captures ahah, for now I’m happy with my Dob though

    Have you tried shooting the andromeda galaxy? It’s bright enough to see with shorter exposures. It’s nothing special, just a blob, but it’s really cool nonetheless

      I mean yeah true but that’s because of the shutter speed I was using and I didn’t want to pick up much noise/ star trailing. Really I need to stack images

  • @jodyschultz5870

    Not sure if you are trolling us but just in case you are not. Use the 300 rule. 300 divided by 1200 (your focal length) is .25 of a second for your max exposure without tracking coz you have a dob.
    Lucky that it's a bright target so this will work with a high ISO. Take 10 or 20 shots as M42 drifts through the frame and then reframe and repeat. Once you have 100 or so take your darks and flats and stack everything in Deep Sky Stacker. If any of that does not make sense. Watch some You Tube videos until it does. You will find that you can produce a much better image. Have fun.
